@文心快码bpf program load failed: permission denied 文心快码 针对你遇到的“bpf program load failed: permission denied”问题,以下是一些可能的解决步骤和考虑因素: 确认用户具有加载BPF程序的必要权限: BPF程序通常需要特定的权限来访问内核资源。如果你不是以root用户身份运行程序,可能会遇到权限问题。 尝试以...

create a skeleton header file, and load with libbpf. The BPF is always compiled from source so less chance that source and instructions diverge. Also resolves issue where libbpf and source get out of sync. The program is only loaded once, so if multiple rules are created ...
